This invention relates to the manufacture of synthetic threads,filaments, bands, ribbons or the like, and, more particularly, to themanufacture thereof by a method in which the synthetic thread or thelike is formed in a coagulating bath. The invention is applicable to themanufacture by a wet method of any synthetic thread, filament, band,ribbon or the like, an example being artificial silk thread manufacturedaccording to a process, such as the viscose, cuprammonium, celluloseacetate or nitrocellulose process, in which a coagulating bath is or canbe used. Staple fiber, artificial horsehair, artificial straw andsimilar products of relatively large denier requiring long periods ofimmersion in the coagulating bath to insure coagulation of the innermostportions thereof are examples of additional articles to the manufactureof which the invention is applicable. Other examples will readily occurto those skilled in the art to which the invention pertains.

By way of illustration, but in no sense of limitation, the inventionwill be described in connection with the manufacture of multiplefilament artificial silk thread produced according to the viscoseprocess. In this process, as in all processes by which artificial silkthread is produced by a wet method, the mass of material from which thethread is formed is extruded into a suitable bath wherein the thread iscoagulated. If the thread is being produced in the conventional manher;i. e., according to either the spool spinning system or the pot spinningsystem, the thread after passing through the coagulating bath iscollected, either on a rotating spool or in a rapidly rotatingcentrifuge, in suitable package form. If the thread is being producedaccording to a continuous system, it is passed, after being spun, tosuitable devices on which it is subjected to various desired processingtreatments, such as washing, desulphurizing, bleaching, oiling, etc.,after which it is collected.

In producing multiple filament viscose artificial silk thread, it is theusual practice to withdraw the thread from the coagulating bath at aspeed of from 60 to 80 meters per minute. Since for various reasons, as,for example, operating convenience, structural limitations, etc., thebath is relatively shallow, the depth of immersion of the spinneretbelow the surface is small and the time of immersion of the thread iscorrespondingly short. As a result, the thread is often incompletelycoagulated when it leaves the bath. In the case of thread producedaccording to the spool spinning or pot spinning system, the coagulationproceeds while the thread is being wound or after it is wound intopackage form, not infrequently resulting in non-uniform coagulation. Inthe case of thread produced by a continuous process, it has been founddesirable to provide means for alloying the coagulation to proceed tosubstantial completion before subjecting the thread to the subsequenttreatments.

It has been known heretofore that beneficial results with regard to thephysical properties of the thread, especially the dyeing qualities, can

be obtained by exposing the thread to the coagulating bath for a periodlong enough to insure substantially complete coagulation before it iscollected and to that end numerous attempts have been made in the pastto increase the period ofimmersion of the thread by increasing thelength of travel of the thread in the bath. This, however, is rendereddiificult by the limited space in the bath trough allowed byconstructional limitations. Attempts to increase the thread travel inthe bath have generally consisted of arrangements of guides or the likeover which the thread has been drawn before leaving the bath. These haveheretofore met with little success, however, because of excessivetensions imposed on the thread, difficulties in starting the threadthrough the guides or the like, lack of space, etc.

'It is an object of the present invention to provide a long coagulatingperiod for synthetic threads, filaments, bands, ribbons or the like bycontinuously storing a relatively long length thereof, preferably in theform of an advancing circular helix, in or in contact with thecoagulating bath.

In the drawings, in which like reference numerals refer to like partsthroughout, Figure 1 is a sectional elevation, from line I-l of Figure2, of a conventional spool spinning apparatus equipped with theinvention, parts being broken away to reveal constructional details;Figure 2 is an elevation of the same device from line 2--2 of Figure 1;Figure 3 is a sectional elevation on a larger scale from line 33 ofFigure 4 of one form of thread-advancing thread store which may be usedto advantage in the practice of this invention; Figure 4 is an'endelevation of the device of Figure 3; Figure 5 is a sectional elevationof a pot spinning machine likewise equipped with the invention, partsbeing broken away to show details of construction; and Figure 6 showsthe invention as applied to one form of continuous spinning machine ofwhich only a portion is shown, other parts being broken away for thesake of clearness. 1

Referring now to the embodiment of the invention shown in Figures 1 and2, the thread I is formed in the usual manner by extrusion of theviscose from the spinneret 2 into a sulphuric acid coagulating bath 3which is contained in trough 4 of a conventional spool spinning machine.In machines of this type there are a plurality of units disposed along acommon bath trough, each consisting of a spinneret and its correspondingcollecting spool; but for clarity only one such unit is shown. Theviscose for each spinneret is supplied through pipe 5 and mass tube 6from a suitable source such as a supply line and pump (not shown). Aguide 'i is preferably provided to guide the thread I from the spinneret2 onto a unitary thread-advancing reel 8 shown completely submerged inthe bath, although it might, if desired, be disposed in any one of avariety of positions, as later described.

On reel 8, the thread is subjected for a relatively long period of timeto the action of the coagulating bath. This is done by temporarilystoring a predetermined lengththereof in a large number of closelyspaced, generally helical turns which are formed and advanced axiallyalong the reel 8 by the action of its elements during rotation. Thethread I, after leaving the reel 8, passes to the collecting spool 9through its associated traverse guide it. It is desirable to provide aguide H to prevent any thread at the discharge end of reel 8 which maybe caused by the motion of the traverse guide if] of the spool 9, asillustrated by the extreme positions it of the guide Ill andcorresponding positangling of the tions l of the thread. In Figures 1and 2 are shown guides and H of suitable design, the operation of whichwill be explained more in detail hereinafter.

The reel 8 may be of substantially the same form and operate in the samemanner as that shown, described and claimed in an application entitledWinding reel, Serial No. 652,089, filed January 16, 1933, by Walter F.Knebusch (Patent 2,210,914).

Referring to Figures 3 and 4, it can be seen that the reel is composedof two generally cylindrical members i2 and i3. Member l2, which may betermed the concentric member, is mounted on a drive shaft l4 with itsaxis concentric with that of the shaft rotation by some means as a setscrew [5. Its periphery is composed of bar-like portions It betweenwhich are slots H. Member l3, which may be termed the eccentric member,is mounted with its axis offset from and inclined to that of member I?and is composed of a spider l8 rigidly supporting bars l9, which aredisposed in slots ll of member !2. The peripheries of members I2 and i3contain the same number of bars, which shaft 28.

M to which it is fixed for It is obvious, of course, that various otherforms of thread-advancing reels, including those with shafts projectingat both ends, might be used in the practice of this invention in lieu ofthe type of reel shown in Figures 3 and 4:.

It has been found advantageous under certain conditions to provide meansfor adjusting the position of the reel so that it may be disposedentirely below the surface of, partly immersed in, or wholly out of thebath. It may, for example, be desired to operate the reel while disposedpartly within and partly without the bath. Also, it is somewhat moreconvenient for the operator, who can thus see while threading orstarting the thread on the reel, to be able to move the reel to aposition in which it is wholly out of the bath. For the purpose ofproviding adjustability, adaptability to conventional spinning machines,as well as portability for the purpose of cleaning, repairing, etc., theapparatus may be constructed as shown in Figures 1 and 2. The particularform of adjusting mechanism shown in Figures 1 and 2, however, forms nopart of the present invention, being shown, claimed and described inapplication Serial No. 235,375, filed October 17, 1938, by Lavern J.Jordan.

In this embodiment of the invention, reel drive shaft M, by means ofwhich the reel 8 is rotated, is positively driven by some means as agear 24 which may be driven through idler 26 by a pinion 2T rigidlymounted on a drive shaft 28, as, for example, by pin 29. Suitable means,as an electric motor 31, may be provided to rotate the drive Motor 31may be mounted in alignment with shaft 28 on a frame 32 extending overthe trough wall 33 on the apron 34 of the spinning machine, which apron34 may be sloped as shown to drain any liquids spilled on it to thewaste trough 35. Drive shaft 28 is journalled, as in bearing 36, inmember 3'! carried by frame 32, the upper portion of which member 31 maybe curved as at to provide a guide portion for the arm 38 mounted in thehousing 39, in which is journalled drive shaft 28.

number should preferably be as large as is posproper construction,operation and maintenance of the reel. Member I3 may be provided with abearing portion, such as a sleeve 2! rotatably mounted on thecylindrical bushing 22 which may be so formed and supported on the framemember 23 that its axis bears the aforesaid offset and askewrelationship with regard to shaft l4.

Rotation of the shaft I4, which may be joursible consistent with thenaled in member 22, thus causes the concentric reel member 12, fastenedto it, to rotate. Eccentric reel member I6 is rotated by contact of itsbars ill with the bars N5 of member I2. The offset and inclinedrelationship of reel members 12 and 13 causes the thread to progress inspaced helical turns axially along the reel in a manner more fullyexplained in said Knebusch application. Any desired predetermined lengthof thread, within reasonable limits, may thus be temporarily stored on athread-advancing reel of this type by suitable construction thereof.Since the reel is supported at one end only, it is of cantilever form inthe sense that'the unsupported end is free of a projecting shaft, whichfeature provides convenience in starting the thread on the reel.

Housing 39 is formed integral with or otherwire rigidly fastened to theframe member 23, which supports reel 8 and the gears that drive it fromshaft 28, and is adapted to be swung about shaft 23 as an axis. Arm 38,which is rigidly mounted on the housing 39, bears a handle assembly 41containing a spring 42 and plunger 43 by means of which the reel is heldin the position corresponding to any of the holes 44 in the curvedperiphery 45 of the member 3'1. It is desirable to provide means such asroller 46, rotatably mounted on arm 38, and roller 41, rotatably mountedon the bracket 48, to support the load exerted by the weight of the reel8 and its supporting and driving means which would otherwise tend tobend the drive shaft 28. A supporting bracket 49 may also be providedfor this purpose. A shield 5l may be provided to protect the reel fromany turbulence that might otherwise be set up by rotation of the gears.

The desirability of guiding the thread as it contacts and leaves thereel is just as great when the reel is swung to the various otherpreviously mentioned positions as when it is wholly submerged. However,when the reel is disposed in these other positions, the thread contactsand leaves the reel at angular positions different from those at thelowermost reel position. This is illustrated by broken lines I of Figure2, which indicate the angular positions of the thread with respect tothe reel when the latter is in position 8" above the surface of thebath.

For thesereasons-the guides I and II may be of the design shown, inwhichthey are curved and mounted on the housing 39, as by lugs 52 and 53, sothat they bear the samerelationship to the reel-8 in-all positions. Itwill be observed that the 'guides perform their function throughouttheentire range of positions of the reel. That is, as the points atwhich the thread-contacts and leaves the reel change, and consequentlythe angularposition' of the thread with respect" to 'the'reelchanges,the thread slides along each guide to the new position, as isillustrated by the position ofthe thread I with respect to the guides 1and II corresponding to reel position 8' of Figure 2. g

In the operation of apparatus of the character shown in Figures 1 and 2,the operator, by means of the adjusting handle II, first swings the reelup "and completely out of the bath to a position such 'asthat indicatedat 8 andstarts the motor 3I'. He then seizes the end of the thread Iformed by the mass issuing from the spinneret 2 disposed in coagulatingbath 3,-passes the thread through guide I and starts it on the reel 8 bywinding it one-or two turns around the reel.

Because the thread is wet, it readily adheres to the reel. Because ofthe action of the reel as it rotates, the thread forms spaced'helicalturns on the reel which are advanced axially of the reel and finallydischarged from the un-' supported end thereof. The operator seizes theend of the thread as or after'it discharges, leads it past guide IIandstarts it on the take-up device, in this case the spool 9 andtraverse guide Ill. The reel is then swung into the bath until itassumes the desired'position, whether wholly or partly immersed.

In the embodiment of the invention shown in Figure 5, the thread I,after being formed in the usual manner by extrusion of the viscose fromthe 'spinneret 2 into the coagulating bath 3 contained in trough4,'passes to the reel 8, on which a predetermined length is continuouslystored in the form of an advancing helix for the purposes of providing"arelatively long period of immersion of the thread in the bath. Thethread, after leaving'reel 8, then passes around the conventional 'godetwheel 54, which may be rotated by some means'as' gears fill/through thefunnel 55 "and thence to the rapidly rotating spinning pot 56.Funnel'55,'which"isrecipro cated vertically by suitablemeans" (notshown), imparts a twist to the thread as it leaves the bottom edgeof'the'funnel and'oauses the thread to be wound in the form of a cakeinthe pot in the usual manner. The 'po t"56 is rotated at the desired highspeed by some means-as a motor' 51. The viscose may be supplied to thespinneret through pipe and mass tube'fi from a suitable source such as asupply pipe and pump (not shown). Guides 1' and II may be provided, if

desired, to guide thethread as it contacts and leaves the thread-storagedevice 8.

The reel 8 may be mounted and driven as shown in Figures 1 and 2 or insome other manner, as, for instance, that illustrated-in Figure 5, inwhich the reel is built in as part of the machine. In the embodimentillustrated, the bushing 22, on which is mounted the eccentric member ofthe reel'and in which is journaled the drive shaft I4, is positioned onthe frame member 23 which is suitably -mounted with-a liquid-tightjoint-om the -bath trough wall 58 Frame member 2 3' is formed with atubular portion extending through the trough wall,- as shown. In theframe member 23 may be positioned a rubber or other suitable bearing 59for shaft I4. The rubber bearing 59 acts as a seal, but liquid whichseeps through between the shaft I4 and the bearing 59 may be collectedin a suitable collecting trough BI which in the case shown is designedtoextend under the outer ends of the bearings of all the reels onthe'machine and fromwhich-the' liquid maybe returned to therecirculating system.

An outer bearing fiZ-may be provided to support the end of the shaft I4and bear the thrust of the bevel gear 63 which drives reel shaft I4 andis driven bygear 64 mounted on drive shaft 65, which may be common toall reels disposed in the trough 4 and which may be driven by anysuitable means (not shown). The bracket which supports bearing 62 mayalso support the trough 6|. A deflecting disc-like member 66 may bemounted on shaft I4 to prevent any liquid which may seep through bearing59 from traveling along shaft I4 to bearing 62. course, that variousother means for mounting the reel 8 and its driving mechanism andsealing the drive shaft I4 may be provided Without departing from thespirit of the invention.

The invention is shown in Figure 6 as applied to a continuous processingmachine. The machine illustrated is a modification of that shown,described and claimed in an application entitled "Manufacture ofartificial silk, Serial No'. 7,114, filed February 18, 1935 by Walter F.Knebusch and AldenI-I. Burkholder (Patent 2,225,642) to which referencemay be made for a more complete description. In the operation of themachine shown, the thread I is formed in the usual manner by extrusionof the viscose from the spinneret 2 into the coagulating bath 3contained in trough 4. To allow coagulation to proceed to substantialcompletion, a predetermined length of the thread is then continuouslytemporarily stored in a plurality of spaced helical turns on a reelBaafter which it passes over the roller '61 or other means for changingthe direction of shown and which bear numbers 68, 63a and 6812,

are arranged in the manner shown in stepped relationship with thethread-receiving end of each reel other than the first directly beneaththe thread discharge end of the preceding reel. The unsupported ends ofthe reels are therefore all presented toan operator at the front of themachine and the helical turns of thread progress to thefront of allreels. The thread stored on each. reel is subjected to treatment by somesuch apparatus as that shown which comprises a suitable reagentdistributor 69 which is supplied by reagent from a supply pip II. Thereagent is showered down on the thread on the reel by the reagentdistributor 69 and collected in a trough I2. Since a machine of thistype may comprise a plurality of such series of reels, of which allreels in the corresponding positions are used for thesame processingtreatments, the "reagent supply pipes --1I and-collecting troughs It isobvious, of

12 may be common to all reels in the corresponding positions.

As examples of possible processing treatments which may be applied tothe thread in a machine of this type, the thread, by the use of suitablreagents, may be washed on reel 68, desulphurized on reel 63a, bleachedon reel 68b and so on, as many reels being used as are required toobtain the desired processing treatments, the thread finally beingcollected by a suitable device. The processing reels may be driven bysuitable means as that shown comprising a main drive shaft 73 providedat intervals with helical gears 14 each of which drives a helical gear15 connected by a shaft 18 through adjustable change speed gears Ti to ashaft 18 extending lengthwise of the machine and arranged to drivecorresponding reels in different series. In the machine shown, aplurality of reels in adjacent series in the corresponding positions aremounted on and driven from the housing E9 in which is disposed the shaft'58 from which each reel is driven by means of a helical gear 81 mountedfor rotation with shaft 18 and meshing with gear 82 which is connectedto the reel drive shaft l4 as by clutch 83.

The manner of mounting and driving th reel 8a immersed in thecoagulating bath may be similar to that shown in Figure and no detaileddescription is therefore required. The drive shaft 65, which rotates thegears 63 and 54 which in turn rotate each coagulating reel 8, may bedriven by some means such as gear 84, shown in broken lines, adapted tobe driven through change gears 85 from helical gears similar to 14 andE5 which are contained in a housing 9! and which are driven from themain drive shaft 13. The shaft 86, from which each spinneret pump 8'! isactuated, may be rotated by some means such as a change gear box 88 bywhich adjustment of the pump delivery may be facilitated, and which maybe driven, as by chain 89, from the gears in the housing 9|.

It is obvious that various changes and modifications may be made in theembodiments herein shown and that numerous other embodiments may bedevised without in any way departing from the spirit of the invention.For instance, though the reels are shown in all the embodiments ascompletely submerged in the bath, each may be so disposed that it islargely, but not entirely, immersed in the bath or even disposed so thatit only dips into the bath to a relatively slight extent. Likewise aplurality of reels disposed entirely in or partly in the bath may beused. Various other means of mounting and driving the coagulating reelsother than those shown may be provided. The reels may be mounted invarious other positions in the bath. For instance, they may be mountedwith their axes parallel or at an acute angle to th longitudinal troughwalls rather than at right angles as shown.

With thread or the like of sufficient strength, it may not be necessaryto supply means for positively driving the coagulating reel since thereel may be rotated and operated by the pull of the thread or the likeas it is drawn off of the reel.

Although. the invention has been shown and described with reference tothe use of devices such as rotating spools, as in Figures 1 and 2,rotating pots and godet Wheels, as in Figure 5, and rotatingthread-advancing reels, as in Figure 6, for collecting or withdrawingthe thread or the like, it should not be construed as limited thereto:various other kinds of collecting or withdrawing means may be usedinstead. In the manufacture of staple fiber, for example, which may bereadily produced according to the present invention, the thread bundleis often collected on a skeining reel. Likewise, various improved formsof apparatus have been devised for producing staple fiber by continuousprocesses wherein the thread bundles are passed from the coagulatingbath through treating devices and to cutting means: the invention may bereadily applied to apparatus of these and other types.

Stretch spinning, which under certain conditions is beneficial becauseit provides increased tensile strength and decreased elongation, may bereadily accomplished by several methods according to this invention.

As examples, the reel may be so constructed that its diameterprogressively increases from the receiving to the thread discharge end,in which case a limited amount of stretching is obtained as the threador the like travels across the reel. Under such circumstances, a flaredreel of the type identified by reference character 8a in Figure 6 mayadvantageously be substituted for the generally cylindrical reels 8employed in the embodiments of the invention illustrated in Figures 1, 2and 5. Also, by rotating the reel at a suitable speed so the thread orthe like will be drawn from the spinneret at a rate greater than that atwhich it is extruded, stretch spinning efiects may be obtained.

In addition, stretch spinning effects may be obtained in the case of thespool spinning system by rotating the spool at a speed which tends todraw the thread or the like from the reel more rapidly than it isdischarged from the reel. In the case of the pot-spinning system, asimilar stretch effect can be obtained by regulation of the relativespeeds of the godet wheel and the coagulating reel. In the continuousspinning system, a like effect may b obtained by suitably regulating thespeed at which the thread or the like is drawn from the coagulatingreel, as by the following reel.

It is obvious that various modifications in the reel herein describedmay be devised; also, that any other unitary thread-advancing threadstore device may be used on which the thread or the like by the actionof the elements thereof is caused to advance in spaced helical turns.Other modifications and advantages of the invention will be apparent tothose skilled in the art. It is to be understood that the invention isnot restricted only to the manufacture of multiple filament artificialsilk thread, for, as has been previously mentioned, it may be used inconjunction with the manufacture by a wet method of any syntheticthread, filament, band, ribbon or the like in which it is desirable toobtain a long travel of thread or the like in the coagulating bath.
